This server and CA both use elliptic curve technology. Non-hybrid, pure elliptic curve. According to crypto marketing, this is the future of public key cryptography. It is thus important that new applications support it. For this test, you need our Elliptic Curve CA certificate.

Test 32 certificate. Notice the absence of any RSA cryptography in this certificate and the key pair.

All the tests, including keys and certificates, are available on Github.

That's also where you will find all the current tests while waiting for us to write documentation here.

What is TLS?

"The TLS protocol provides communications security
over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery."
From RFC 5446 that defines the current TLS - version 1.2. Wikipedia is also a good help in explaining TLS.
